Title: Method of evaporating and condensing a volatile component, particularly for recovery of solvent in printing processes, and apparatus for carrying out the method
IPC: B01D5/00
Filed: 1978-11-02
Abstract: A method and apparatus for evaporating and condensing a volatile component is provided, particularly suitable for recovering printing ink solvent.

Title: Security switch with test facility
IPC: G08B13/08
Filed: 1981-07-08
Abstract: A security switch (12), for example one for mounting on a door frame (22) to be switched ON by the opening of the door (21), has one or more holes (18, 19) in its housing (15) aligned with housed conductors (16, 17).

Patent GB-2086994-A (GB)
Title: Fuel injecting pumping apparatus
IPC: F02M41/14
Filed: 1981-09-15
Abstract: A liquid fuel injection pumping apparatus of the rotary distributor type has two forms of cam lobe on its cam ring. The first form of cam lobe is a pumping lobe 45 which can effect inward movement of a plunger to achieve pumping of fuel and after the crest of the lobe has been passed allows outward movement of the plunger to lower the fuel pressure in the various passages in the apparatus. The other form of lobe is a holding lobe 46 which whilst one plunger is being moved inwardly holds another plunger against movement. When the crest of the holding lobe is reached the associated plunger is allowed to move outwardly and this movement is arranged to take place shortly before the end of the inward movement of the plunger associated with a pumping lobe. The effect is to reduce the period towards the end of fuel delivery at which fuel is supplied at a reducing rate. <IMAGE>
Patent GB-2092181-A (GB)
Title: Spray treatment apparatus for small workpieces
IPC: C23C22/00
Filed: 1981-12-24
Abstract: The apparatus, for example for washing and rinsing, comprises several containers (11, 12, 13) arranged for rotation about a common axis (14) and each having an internal generally helical screw feed. Each barrel tapers from its intake end (15) to its output end (16), which is disposed within the intake end (15) of the next container, to feed workpieces directly. The axis (14) is horizontal and the containers can be rotated independently. Spray heads carrying treatment liquid are spaced from the intake end of each container so that treatment liquid flows back in countercurrent to the workpieces to the intake end (15) where it is collected, filtered and recycled to the spray heads. By using tapered containers the need for inclining containers and for each container to be larger than a preceding container is avoided. <IMAGE>
Patent GB-2091956-A (GB)
Title: Clamping devices for testing conductor plates
IPC: H05K13/08
Filed: 1982-01-19
Abstract: For electrically testing conductor plates (13) such as circuit boards fitted with components, individual conductor tracks must be tapped by means of contact pins (15). A resilient sealing strip (21) at the periphery of a board (13) to be tested permits it to be clamped in position by applying a reduced pressure on one side. When this occurs, the conductor plate (13) bears against the resilient contact pins (15) and a support plate (3). A base plate (1) carries guide sleeves (14) for the contact pins (15). The support plate (3) and the base plate (1) bear against each other by way of a net (20) and form between them a reduced-pressure space (9) which is connected to a vacuum pump by way of conduits (10, 11). The air between the conductor plate (13) and the support plate (3) is also sucked away through bores (16). This causes the conductor plate (13) to be pressed against the contact pins (15) by the external air pressure. <IMAGE>
